What is Tencent Cloud Lightweight Application Server? What are the differences between lightweight and CVM cloud servers? What is Tencent Cloud Lightweight Application Server? The lightweight application server is an out-of-the-box lightweight cloud server launched by Tencent Cloud. It is suitable for individual developers or small and medium-sized enterprises. What is the difference between Tencent Cloud lightweight server and cloud server? Why are lightweight application servers cheaper? Is it because the CPU and memory performance of the lightweight server is worse than that of the CVM of the cloud server? The lightweight application server is suitable for small and medium-sized enterprises or individual developers to build corporate official websites, blog forums, WeChat applets, or development and testing environments. The cloud server CVM is suitable for more complex application scenarios such as high-concurrency websites, big data computing, and machine learning. Tencent Cloud Server Network explains the differences between Tencent Cloud Lightweight Application Server and Cloud Server CVM in terms of performance testing, network bandwidth, billing mode, application construction, and suitability for users.
Tencent Cloud Lightweight Application Server is a new-generation cloud server that is quickly built, easy to manage, and cost-effective based on the cloud server CVM. Like some small and medium-sized enterprises or individual developer users, there is no need to choose a cloud server for a simple application architecture. . The biggest advantage of cloud servers over lightweight application servers is that cloud servers can build high-availability and high-disaster recovery cluster applications with instances such as load balancing and cloud databases. However, not all application scenarios require professional-grade cloud server CVM As a basis, for most light-weight application scenarios such as website web application scenarios, WeChat applet servers, cloud disks, APP client development, e-commerce applications, cloud disk image beds, etc., a lightweight application server is enough, and the focus is on cost Low. In 2bcd.com/go/tx/, there is a detailed configuration and accurate quotation table. In addition, lightweight application servers are a trend, and major cloud vendors are flocking to them. Not only Tencent Cloud, Alibaba Cloud is the first to launch lightweight application servers. Huawei Cloud's Yunyao Cloud Server HECS is also a lightweight cloud server. Baidu Smart Cloud's lightweight application server is in beta testing.
1: Performance difference between lightweight application server and cloud server
Why are lightweight application servers cheap? Is the lightweight server worse than the cloud server? No, compared with the standard cloud server CVM of the same specification, the CPU and memory performance of the lightweight application server are at the same level as the standard cloud server CVM . As shown below:
Note: The unified performance level is compared with the standard cloud server CVM instance. If compared with the high IO type, heterogeneous GPU, and computing cloud server CVM instance, the performance is still different.
Two: Comparison of main frequency differences of CPU models
When creating a lightweight application server, it is not supported to specify the CPU model of the underlying physical server . Tencent Cloud will randomly allocate a physical CPU model that meets the package specifications, and usually prefer a newer generation CPU model. CVM instances with different specifications of cloud servers have specified CPU models and main frequencies (refer to: Description of CPU processor models with different specifications of cloud server CVMs ).
There are currently 2 lightweight application servers under the Tencent Cloud account of the lightweight server network, check the CPU processor model and main frequency.
The lightweight application server tested in this article is a Hong Kong lightweight server with 1 core and 1G30M bandwidth of Tencent Cloud. The CPU model used is Intel(R) Xeon(R) CPU E5-26xx v4 with a main frequency of 2.4G Hz. At present, the lightweight server with 2 cores and 4G6M bandwidth is popular at the event. The CPU processor generally uses Intel(R) Xeon(R) Gold 6133 CPU with a main frequency of 2.5GHz and a turbo frequency of 3.0GHz.
Three: Public network bandwidth comparison
Tencent Cloud Lightweight Application Server is sold as a package, and the cloud server CVM can customize the bandwidth of the public network. Lightweight Server Network believes that the CVM public network bandwidth of the cloud server is better than that of the lightweight server. The bandwidth of the lightweight application server is the peak bandwidth. The amount of server bandwidth has a monthly traffic package limit ; while the cloud server CVM public network bandwidth is exclusive, as much bandwidth as you buy will be exclusive to you. The public network bandwidth of the lightweight application server is limited by the monthly traffic package, as shown in the figure below:
Lightweight application servers are purchased according to packages. The CPU memory, bandwidth, and system disk packages officially provided by Tencent Cloud cannot be customized and can only be purchased according to the package, and the public network bandwidth is limited by the monthly traffic package. The traffic of the monthly traffic package in the package needs to pay the traffic fee separately, and the traffic price per GB is about 0.8 yuan. Reference: Tencent Cloud Lightweight Application Server Configuration Quotation and Traffic Pack Overage Charges .
Four: Monthly traffic comparison
The public network bandwidth of the cloud server CVM does not limit the monthly traffic. Lightweight applications are sold according to packages. 198 yuan for 15 months, 628 yuan for three years, 500GB monthly traffic, the traffic generated in the monthly package is free, and the excess traffic needs to pay additional traffic fees, the price is 0.8 yuan per GB. The traffic price of the light server is different in different regions, and the traffic price of the light server in different regions is as follows:
| region | Price (yuan/GB) |
|---|---|
| Mainland China, Singapore, Tokyo, Frankfurt, Seoul | 0.8 |
| China Hong Kong | 1.0 |
| Mumbai | 0.58 |
| silicon valley | 0.5 |
But don’t worry, generally speaking, the monthly traffic that comes with a lightweight server is enough. Like the lightweight server under the cloud server account, the monthly traffic is not only inexhaustible, but also has surplus. Of course, if it is a video application, it is definitely not enough.
It should be noted that the billing traffic of the lightweight application server refers to the outbound traffic of the public network, and the private network traffic and the inbound traffic of the public network are both free, so you don’t have to worry about traffic. The lightweight server traffic charges and free instructions
Five: Comparison of price differences between lightweight servers and CVM cloud servers
Tencent Cloud's lightweight application server has high configuration and low price, and the public network bandwidth starts at 4M.
For the preferential price of Tencent Cloud Server CVM, please refer to the official page . With the same CPU memory configuration, the price of Cloud Server CVM is more expensive.
Six: Differences in Billing Modes
Ateng Cloud has already said earlier that lightweight application servers are sold as packages, with fixed CPU, memory, bandwidth, and system disk configurations, and only support the yearly and monthly billing model. Users can choose the corresponding package according to their actual needs. The cloud server CVM supports multiple billing modes, such as pay-as-you-go, subscription, and bid instances. In addition, the cloud server CVM instance specifications, CPU memory, bandwidth, and system disk configurations can be freely selected by users. Reference: https://cloud.tencent.com/document/product/213/2180
Seven: The difference between the system disk
All series of lightweight application servers are equipped with SSD cloud hard disks as standard, while cloud server CVM system disks or data disks can choose high-performance cloud hard disks, general-purpose SSD cloud hard disks, or SSD cloud hard disks. In terms of hard disk storage, lightweight application servers have more advantages. In addition, it should be noted that the cloud hard disk of the lightweight application server and the cloud hard disk of the cloud server are independent of each other and do not support mutual mounting.
Eight: The difference between cluster applications and intranet connectivity
The intranet connectivity of lightweight application servers is poorer than that of cloud servers. Cloud servers can be connected to load balancing instances, cloud database instances, and intranets to build high-availability cluster applications. Lightweight application servers are generally used for stand-alone applications that only require one cloud server. The cloud server can create a private network VPC, and plan and maintain the network on the private network by itself, such as specifying a private network IP address, planning an intranet, creating a switch, and other functions.
Lightweight servers do not support secondary virtualization or installation of virtualization software, while Blackstone physical servers support secondary virtualization. Tencent Cloud Lightweight Application Server has the concept of availability zone, while Alibaba Cloud Lightweight Server has no availability zone to choose freely. In terms of intranet connectivity, lightweight application servers are worse than cloud server CVMs. The cloud server CVM has the concept of availability zone, but the lightweight application server cannot freely choose the availability zone. And after the lightweight application server instance is created, changing the intranet IP address is not supported. In the past, the lightweight server did not support changing the public network IP address, but now it supports changing the public network IP. Lightweight does not support user-defined configuration of private network VPC, and the network is automatically created and allocated by the system.
Nine: Cloud server system image differences
The lightweight application server provides an application image template, and users can build the required program and the configuration environment that the program depends on with one click through the application image.
The lightweight application server has lower barriers to use and provides application mirroring. Using the application mirroring, you can install the required programs and operating environment with one click. The application mirrors supported by the lightweight application server include: Pagoda Panel, WordPress, SRS, Room Service, Discuz, Typecho , Cloudreve, LAMP, Node.js, ASP.NET, Theia IDE, Docker, K3s, etc. The cloud server CVM image supports public images, custom images, shared images, and image markets.
Application mirroring is very convenient. Taking WordPress as an example, select WordPress as the mirror image. After the cloud server is created, the WordPress blog site can be launched. It does not require users to build the web environment required by WordPress, nor does it need to manually install the WordPress program. Using the application mirroring website Go online in minutes.
Ten: Cloud server CVM and lightweight application server are suitable for people and application scenarios
The lightweight application server is suitable for small and medium-sized enterprises and individual developers; while the cloud server CVM is for all cloud users. The threshold for using cloud servers is higher, and it is more suitable for applications such as individuals and enterprises with certain open capabilities. Cloud servers are suitable for complex application scenarios, such as high-concurrency websites, large-scale games, complex distributed cluster applications, video codecs, big data analysis, machine learning, deep learning, etc.; lightweight application servers are more suitable for simpler stand-alone applications , such as corporate websites, blogs, product display websites, WeChat applets, general web application scenarios, mobile APPs, applets, cloud disks, picture beds, cloud development and testing environments, and learning environments.

Previously, the Tencent Cloud lightweight application server did not support changing the public network IP address, but now it is possible to modify the IP address, and it also supports mounting cloud hard disks. As time goes by, the lightweight application server will support more functions. The performance of a lightweight application server is similar to that of a standard cloud server CVM instance. The point is that the price of a lightweight application server is much lower than that of a cloud server. More and more users choose a lightweight application server. The newly added functions of the lightweight application server are as follows:
- Tencent Cloud Lightweight Application Server already supports changing the public network IP address ;
- A lightweight application server can record 5 website domain names, and if it is an enterprise user, it can apply for 2 record service numbers;
- Lightweight application servers already support cloud hard drives .
Twelve: CPU memory bandwidth system disk configuration upgrade difference
Lightweight application servers are sold in the form of packages. The CPU, memory, system disk, and public network bandwidth configurations are fixed. Therefore, if the configuration is not enough, you can only upgrade the package. You cannot upgrade the bandwidth, CPU, memory, or system disk separately. It can be upgraded to a package as a whole, and the lightweight application server can only be upgraded and cannot be downgraded.
Cloud server CVM upgrade or downgrade is supported, and it is very free. You can upgrade the CPU, memory, and public network bandwidth independently, and downgrade is supported. Reference: Cloud Server CVM Adjustment Instance Configuration Tutorial .
Thirteen: Instructions for changing the IP address
The lightweight application server supports the replacement of the public network IP , but does not support the replacement of the private network IP, nor does it support the binding of the elastic public network IP . In addition, when creating a lightweight application server instance, a MAC address will be randomly assigned, and the MAC address cannot be specified.
Fourteen: Description of IPv6 Support
The lightweight application server does not support IPv6, but the cloud server CVM supports IPv6.
Fifteen: Differences between firewalls and security groups
Opening or disabling ports on the lightweight application server is done in the firewall , and opening or closing ports on the cloud server CVM is configured in the security group .
